These specimens belong to a species which might be regarded as 

 an intermediate between tolteca a,\\di paraensis, combining characters 

 of both, with some peculiarly its own. 



It differs from both in the greater width across the coxal lobes; 

 from tolteca in the comparative narrowness of the median and poste- 

 rior sections of the prothorax, in the form and arrangement of the 

 foliaceous lobes of the second and third femora and tibise, and in 

 the general greenish color of the elytra ; from paraensis ( 9 ) in the 

 form of the elytra (thus agreeing with tolteca), in the comparatively 

 small size of the frontal processes (like tolteca) and the reduced size 

 of the spines on the prothorax. 



%. — Form rather slender and graceful. Frontal processes rather short, de- 

 cidedly conical. Antennae pectinate. Prouotura slender, the shaft reniarkahly 

 so and triangular in section; the collar rather broad, coxal lohes decidedly so; 

 the shaft sharply keeled, obscurely sulcate, moderately spined. Elytra long and 

 narrow, marginal field moderately developed anteriorly. Median femora and 

 tibiae with the foliaceous lobes developed, one on tlie femora posteriorly, two on 

 the tibiae (anteriorly and posteriorly), those on the femora very angular. Poste- 

 rior femora each with a trace of an anterior lobe, the posterior one somewhat 

 rounded ; tibiae with an elongated lobe on the external margin. General color 

 of head, pronotuni and limbs blackish brown ; the anterior pair of limbs dusted 

 with ashy, median and posterior pair each with a single baud of ochre. Beneath 

 light brownish ; the inner side of the anterior femora pale yellowish. Abdomen 

 rich glossy t)lackish brown, with marginal patches of ochraceons. Elytra gi'een- 

 ish ; the marginal field almost opaque, the color rich ; discoidal field semi-hyaline, 

 the color faint, with a large central brownish blotch flanked anteriorly and pos- 

 teriorly by two smaller ones, besides a few irregular spots scattered near the tip. 

 Wings hyaline, infuscated at the tip with a few small irregular blotches .scattered 

 over the anterior portion. 



9 • — Form moderately heavy. Frontal processes as in the male. Pronotuni as 

 in the male, but with a greater width to the shaft. Elytra with the marginal 

 field sharpljf rounded, making it only three-fourths the length of the discoidal 

 area. Abdomen depressed. Posterior femora with the anterior lobe much elon- 

 gated, having a length of about four millimeters. General color of the head, 

 pronotum and limbs soiled sienna. Head and pronotuni lined and shaded with 

 umber. Elytra opaque pea-green, richest on the marginal area, the discoidal with 

 two large blotches of reddish brown, several small spots of the same irregularly 

 scattered over the posterior portion : the internal fold of the posterior margin 

 blackish brown. Wings smoked with blackish purple, the cross-veins white; 

 tips of the wings tinged with sepia; the anterior border ochraceous. Abdomen 

 glossy brownish black ; below dull black, with the tip oi'ange. Femora and tibiae 

 banded with clear ochraceous, richest on the anterior pair of limbs, rather ob- 

 scure on the posterior pair.
